x (3x2 – 108) ÷ 3x (x – 6) = …………….. A) x – 3 B) 6

1.	x (3x2 – 108) ÷ 3x (x – 6) = …………….. A) x – 3 B) 6 + xC) x + 6 D) 6 – x
Answer» Correct option is C) x + 6 Correct option is (C) x + 6 \(x(3x^2–108)\div3x(x–6)\) \(=\frac{x(3x^2–108)}{3x(x–6)}\) \(=\frac{3x(x^2-36)}{3x(x–6)}\) \(=\frac{3x(x-6)(x+6)}{3x(x–6)}\) = x + 6

x (3x2 – 108) ÷ 3x (x – 6) = …………….. A) x – 3 B) 6 + xC) x + 6 D) 6 – x

Answer»

Correct option is C) x + 6

Correct option is (C) x + 6

\(x(3x^2–108)\div3x(x–6)\) \(=\frac{x(3x^2–108)}{3x(x–6)}\)

\(=\frac{3x(x^2-36)}{3x(x–6)}\) \(=\frac{3x(x-6)(x+6)}{3x(x–6)}\)

= x + 6
